Barbara is one of the investors on ABC's hit show Shark Tank, and has been with the show for all eight seasons. The businesswoman isn't the first of ABC's Sharks to compete on DWTS, as Robert Herjavec was part of the season 20 cast, and while he didn't win the mirrorball trophy, he landed himself a wife in pro partner Kym Johnson.

Victoria, 22, is a former Paralympian swimmer who currently works as TV personality for ESPN. Victoria then "10 years in a wheelchair paralyzed from the waist down," she wrote in a piece for ESPN, before competing with the USA Paralympic swim team at the London Games, taking home three silver medals and a gold medal.

Victoria began walking in 2015, before finally taking her first step without the assistance of a crutch in 2016, writing, "I haven't stopped since."
